Question

Advantages and disadvantages of hyv seeds?

Answer 1

Disadvantages of HYV seeds:-

The major disadvantage associated with HYV seeds is bigger requirement of irrigation facility, chemical fertilizers and pesticides to produce best quality yield. Higher yields are possible only from the combination of HYV seeds, better irrigation facility, good amount of chemical fertilizers and pesticides.Excessive use of chemical fertilizers and pesticides degrade our environment by killing necessary bacteria present in the soil and hence the soil becomes unusable. If heavy amount of chemical fertilizers, pesticides and water is used then the cost of farming will also increase. the poor farmers are unable to buy HYV seeds, so HYV seeds are of no use to them. Most of the farmers in India are very poor and own very small piece of land, so they can't afford to purchase HYV seeds.
